My boyfriend and I were having a cigarette on his 2nd floor balcony. We like to watch birds with his binoculars. The apartment is next to the Griffith Park Observatory area.

We saw a shiny circular object in the sky. He grabbed his binoculars and took a peek. He said he couldn't tell what it was...then he saw another one. We both watched and saw one go up and the other one went down. Then we couldn't see them anymore. We figured they were shiny balloons or something, but then thought HOW would one go up and one down?

Also, if they appeared quite visible from where we were then they would HAVE to be quite large.
